- The results were generated from 5 mock replicates
- Each replicate was generated by randomly splitting the subjects in two mock groups
- No sub-sampling of cells per patient was performed for this data
- DE was introduced by randomly swapping genes in one of the mock groups
- The number of patients was randomly sub-sampled stratified by mock group
Note that for n_patients 10 and 20, the
selected patients vary randomly between the replicates, which is why the
nrows and ncols are not identical. For the
n_patients 30, however, no random sub-sampling was done
because I could just use all patients from 2 out of the original 3
batches from the Control samples. That’s why the ncols are
identical for those subsets.
The mock group assignment of each subject also varies across replicates.
